ICE-PIQK SCABBARD.

Specification of Letters Patent. Patented Aug. 14E, 1917.

Application filed April 3, 1917. Serial No. 159,574.

To all whom it may concern: v

Be it known that I, JOHN B. MARTELLI, a subject of the King of Italy,residing at 537 East 83rd street, New York city, in the county of NewYork and State of New York, have invented new and useful Improvements inIce-Pick Scabbards, of which the following is a specification.

This invention relates to ice picks, and more especially to the cases orsheaths in which the same are mounted; and the object of the inventionis to produce a scabbard or protector of peculiar formation which willpermit the escape of the water of condensa'tion gathering on the pick sothat the latter will not become rusted and which so far as possible willprotect the user from injury and the pick itself from dust and germs.

It is the purpose of the present invention to produce a scabbard ofpeculiar formation whereby the water of condensation will be permittedto escape and whereby the pick will be protected and the user will beprotected from the pick, and in this connection l I employ a specialform of fastening between the scabbard and the handle so that the partsmay not accidentally become'detached but may be disconnected immediatelywhen desired. y

Details are set forth in the following specification, reference beingmade to the accompanying drawings wherein 'z- Figure 1 is perspectiveview of this improved device in its simplest form.

Fig. 2 is a central longitudinal section showing the shape of the innerwall of the scabbard, and how all parts therein descend toward an outletopening when the tool lies on a flat surface.

Fig. 3 is a fragmentary perspective of the inner end of a scabbardshowing fasten ing means of slightly different form, and Fig. l is aperspective view of the handle portion of the device coacting therewith.

We are not concerned with the structure of the handle I-I-into which isinserted the blade or bodkin B, held therein by a ferrule F. The bladeor pick proper tapers to a point P at its outer end, and theconstruction and use of ice-picks is too well known to needamplification.

Coming now to the present invention, the scabbard l is a hollow affairof suficient length to inclose the blade, externally round or oval asmay be desired, closed and preferably rounded at its outer end 2, andprovided With a bore?) which preferably tapers toward its inner endvwhere it fits closely around the blade at the point 4L. The bore alsormay taper toward the other end near the point 2, as best seen in Fig. 2,and the result is that the bore is larger at its midlength at about thepoint 5s Here its wall is pierced with two openings 6, and it will beobserved that when the tool lies on a level surface indicated by theline 7, even though its inner end is canted up a little by the handleI-I, all portions of the interior of the scabbard descend slightlytoward the open` ing 6. The result is that moisture on the blade B whichcondenses thereon or drips V therefrom, will -fall into the bore of thescabbard and will run out the opening 6to a large extent.

While the scabbard above described 'is obviously slipped over the bladewhen the latter is not in use,and possibly might be held with somefriction thereon at the point 4, I prefer to provide fastening meansbetween the hooks ll and the latter snap behind it and the parts arefastened together As shown as seen in Fig. 2. I would not have the hooksvery decided, and therefore the scabbard may be. jerked out of positionbetween them; but if they do too reliably engage the rib, they may bepressed apart by the fingers and the scabbard withdrawn.

In Figs. 3 and l is shown a slight amplicationof the idea for purposeswhich will be made plain. I-Iere the scabbard is flattened on oppositesides as indicated at 20, and on lines directly in line with the holesor openings 6, the attened portions or faces extending completelythrough the rib 12 which latter is therefore divided into two ribs, eachextending around-perhaps onel0 whose front ends are hooked inward as atll to engage the ribs on the scabbard, and in this case the jaws may berigid if desired-in fact the entire handle could be stamped or cast froma rather' thick block of metal, and the tempered blade or bodkin may beinserted and welded or otherwise secured in place as desired. Thescabbard is obviously connected with the hooks 1l by passing its flatfaces 20 between their inner ends and then giving it a quarterrevolution to bring its ribs l2 behind said hooks, and the parts are sodisposed and proportioned that at this time the smaller inner end 4E ofthe bore of the scabbard lits rather closely around the larger inner endof the blade B. Having given the scabbard such partial rotation, theholes 6 are disposed opposite the liat faces of the handle I-I. Now whenthe tool is laid` aside, the flat handle will not stand on edge. In thatposition the axis of the scabbard would be so tilted that moisturewithin the same would run down into its point rather than escape throughthe openings 6. The purpose of flattening the handle is therefore tomake the device lie as seen in F ig. 2, so that moisture may escape inthe manner above described. Moreover a handle so constructed is somewhatcheaper than the average handle made of wood, but with respect tomaterials and proportions, and other details, I do not wish to belimited. The essential feature of this amplification of the idea isthat, whereas the structure shown in Fig. l would permit the sca'bbardto be slipped onto the blade and left with the openings at the sidesrather than the top and bottom, this structure requires that when thescabbard is latched to the handle the opening 6 must be vertical andmoisture will escape.

What is claimed as new is l. The combination with an ice pick comprisinga blade and a relatively flat handle; of a scabbard having twodiametrically op- `Josite moisture-outlet openings and its bore einglarger adjacent said openings and tapering in both directions away fromthem, and fastening devices between the contiguous ends of the scabbardand handle so disposed axially of these elements as to be engaged whensaid outlet openings stand vertical, for the purpose set forth.

2. In an ice pick, the combination with a blade, a flattened handle towhich its base is attached, and oppositely disposed jaws projecting fromthe inner' end of the side edges of the handle alongside the blade andyhooked inward at their forward extremities; of a scabbard rotatably andremovably inclosing the blade and flattened at its inner end on oppositesides so as to pass between said hooks, its body having diametricallyopposite moisture-outlet openings in line with said flattened portionsof the scabbard, and ribs on the exterior of said inner end between theliattened portions', for the purpose set forth.
